The synthesis of new 2-(3-bromo-5-isoxazolylideneamino-oxy)acetic acids and their condensation derivatives with suitable beta-lactam nuclei is reported. Their antibacterial properties have been tested in vitro. An interesting activity against Gram-positive bacteria including beta-lactamase-producing microorganisms was found among the cephalosporanic acid derivatives.
